I was down there on Thursday
I rode on the opposite side from the tree farm, and it was great, though a little bit on the muddy side. Being less familiar with that side I missed some parts, but as far as I can see, the develpment has not really touched that side.
On the tree farm side, it's another story. I hadn't been down there for over a year, and I was pretty bummed by what I saw. You can still do a bunch of riding on that side but there is one huge bulldozed area and bulldozers have kind of pushed some tracks through.
The guys at the bike shop said it will be years before the trails are completely gone. But iI would say it is the beginning of the end
